	<h1>AutoComplete Control: Query a JavaScript Function for In-memory Data</h1>
	
	<div class="exampleIntro">
	<p>This example uses a DS_JSFunction DataSource pointing to a JavaScript function
that returns data as an array of strings. Since the data for this example is
already loaded into memory, queries should be very fast to return data,
and since there is no server load concern, the AutoComplete instance can be
configured to have a query delay of zero seconds.</p>

<p>In this example, the AutoComplete instance is able to keep its container
always open by customizing the appropriate CSS styles and enabling the
<code>alwaysShowContainer</code> property. We hook into the custom events
<code>containerExpandEvent</code> and <code>containerCollapseEvent</code>
and calling the <code>setHeader()</code>, <code>setBody()</code>, and
<code>setFooter()</code> methods to dynamically update the contents of the open
container. Finally, the AutoComplete's <code>formatResults()</code> method
has been customized to display multiple data fields in the container.</p>
